  • and similar European

    Audi

    Carbon cleaning, water pumps, valve covers, timing chains — proven on the European platforms.

  • or equivalent parts

    OEM

    We source for fit and longevity. Quality parts are the cheapest repair over the long run.

The full menu

Five repair specialties, one shop.

Most shops are good at two or three of these. Pro Tech runs the full menu — including the involved European work and the engine internals other shops turn away.

01 · Repair specialty

Brakes

Pads, rotors, calipers, lines, ABS

Quiet, predictable stopping power. Pads and rotors are the common job — but we also handle the calipers, the master cylinder, the lines, and the ABS diagnostics that show up when the easy parts don't fix it.

  • Brake pads and rotors
  • Calipers and caliper hardware
  • Brake fluid service
  • Hydraulic lines and hoses
  • Master cylinder + booster
  • ABS diagnostics

02 · Repair specialty

Suspension

Struts, shocks, control arms, bushings

Bring back ride quality, even tire wear, and confident handling. Suspension repair pairs with an alignment to put the geometry back where the factory specified.

  • Strut and shock replacement
  • Control arms and ball joints
  • Bushings (sway bar, control arm)
  • Tie rod ends
  • Wheel bearings
  • Alignment coordination

Transmission

Service, diagnostics, repair

Catch transmission concerns early — hard shifts, slipping, delayed engagement — before they become a rebuild. We service and repair automatic and manual transmissions, and coordinate full rebuilds with trusted specialists when that's what the diagnosis calls for.

  • Fluid and filter service
  • Leak repair
  • Hard-shift and slipping diagnostics
  • Solenoid and sensor repair
  • Clutch replacement (manual)
  • Rebuild coordination

Engine repair

Timing chains, valve covers, internals

Involved mechanical work. Timing chain protection, valve cover replacement, gaskets, and internal repair on engines other shops would quote as a swap. We take the work and we explain it.

  • Timing chain and tensioner
  • Valve cover replacement
  • Head gasket and head work
  • Water pump replacement
  • Carbon cleaning (direct injection)
  • Internal engine diagnosis

European auto service

Audi and similar — proven capability

European cars need a shop that's done the work before. Pro Tech handles Audi and similar platforms with the same structured diagnostic approach and involved mechanical capability — without the dealership invoice.

  • Carbon cleaning (direct injection)
  • Water pump and thermostat
  • Valve cover and seal work
  • Timing chain protection
  • European-specific diagnostics
  • Audi, BMW, Mercedes platforms

Where we differ

Jobs other shops won't touch.

Timing chains. Carbon cleaning. Valve cover replacement. Internal engine work. Audi and other European platforms most independent shops decline. We take the work, we explain the work, and we stand behind it.

Local Guide · a year ago · BMW 4 Series · Mazda CX-9

I couldn't be more impressed with the amazing service at Pro Tech Auto LLC! They did incredible work on both my BMW 4 Series and my wife’s Mazda CX-9. The team was professional, thorough, and went above and beyond to ensure both vehicles were in top condition. For my BMW, they handled everything with care and precision, from diagnostics to repairs, and it drives like new again. My wife’s Mazda CX-9 also got the royal treatment, and we couldn’t be happier with the results. Special thanks to the entire team for their honesty, expertise, and attention to detail. Pro Tech Auto is now our go-to place for any car repairs or maintenance! Highly recommended!

FAQ

Repairs FAQ

What Manchester drivers ask about heavier mechanical work.

  • 01

    Do you work on European cars like Audi, BMW, and Mercedes?

    Yes. European service is one of our specialties — carbon cleaning, water pump replacement, valve cover work, timing chains, and diagnostics. Audi and similar platforms get the same structured diagnostic approach as everything else we work on.

  • 02

    I was told my engine needs to be replaced. Can you give a second opinion?

    Yes — and we frequently find that involved repair (timing chain, valve cover, water pump, head gasket) resolves what another shop quoted as an engine swap. Bring the diagnosis and any inspection notes; we'll evaluate honestly.

  • 03

    How long do brakes typically take?

    Pads and rotors on a standard vehicle: typically same-day. Calipers, lines, ABS diagnostics, or master cylinder work: one to two days depending on parts and the complexity of the job.

  • 04

    Do you do transmission rebuilds?

    We handle transmission fluid service, diagnostics, leak repair, and many internal repairs in-house. For full automatic transmission rebuilds, we coordinate with trusted specialists — and manage the project so you have one shop to deal with, not three.

  • 05

    What's the warranty on your repair work?

    Standard warranty terms cover parts and labor on most repairs. Specifics vary by job and parts supplier — we'll spell out the warranty in writing on your invoice before you pay, not buried in fine print.

  • 06

    Can you do suspension work and an alignment together?

    Yes. Struts, shocks, control arms, bushings — we replace what's needed and confirm the vehicle is alignment-ready. For the alignment itself we partner with a trusted local shop with a proper alignment rack; we coordinate the handoff.
